lLLUMlNATlNG-TILE.

SPECIFICATION forming part of Letters Patent No. 424,302, dated March25, 1890.

Application filed January 10, 1890- Serial No. 336,480. (No model.)

To all whom it may concern.-

Be it known that I, JACOB JACOBS, of New York city, in the county of NewYork, and in the State of New York, have invented certain new and usefulImprovements in Illumihating-Tiles; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, in which Figure 1 is aperspective View of the body of my tile from the upper side. Fig. 2 is alike view of the same from the lower side. Fig. 3 is a plan view of thecompleted tile from the upper side; and Figs. 4 and 5 are sections uponlines 00 :n and .e' .2, respectively, of Fig. 3.

Letters of like name and kind refer to like parts in each of thefigures.

The design of my invention is to secure the largest light area which ispracticable without impairing the strength of a tile; and

to such end my said invention consists, principally, in a tile which isprovided with octagonal light-openings that are arranged in parallelintersecting rows, and between the diagonally-opposite sides ofcontiguous ootagonal openings has smaller square openin gs,substantially as and for the purpose hereinafter specified.

It consists, further, in an illuminating-tile constructed in the mannerand for the purpose substantially as hereinafter shown and described.

In the carrying of my invention into use I employ a tile A, which isconstructed from metal and is provided with light-openings a and a, thatare octagonal in form and are arranged in parallel rows, as shown. Thearrangement of the light openings a and a causes the four opposite sidesof each to be parallel with the corresponding sides of four contiguousopenings, while between the diagonally-opposite sides of each fouradjacent openings is a square space a, which also constitutes alight-opening, having a considerably smaller size than one of theformer. Between the contiguous sides of the lightopenings is a singlebar a that has no greater thickness than is necessary in order to securethe requisite strength for the tile, by which construction the surfaceof such tile is given the largest practicable light area and presents nodead or waste space. At their lower edges each bar a has a flange of,that projects horizontally inward into each lightopening and forms abearing for a lens B, which lens is placed thereon and is secured inplace by filling the space between its sides and the contiguous sides ofits opening with a suitable cement O in the usual manner. Such lensesmay correspond in shape to their openings, or their upper portions maybe round,if desired. The edges of the tile have each the form shown, andwhen caused to abut against the corresponding edge of a11- other tileform between a series of square light-openings a and a. In order thatsuch openings may not be obstructed,the supporting-bar D should beenlarged at such points and provided with square openings (1 and d, thatcorrespond in size to the space within the ledge or bearing a of anopening in the body of the tile.

While glass lenses are preferably fitted into the square openings a anda, tiles or any other material may be placed therein, if desired.

I prefer to have the supporting-bar D entirely covered by the tiles andcement; but, if desired, said bar may extend to and form part of thecompleted surface.

Having thus described my invention, what I claim is- 1. A tile which isprovided with octagonal light-openings that are arranged in parallelintersecting rows, and between the diagonallyopposite sides ofcontiguous octagonal openings has smaller square openings, substantiallyas and for the purpose specified.

2. An illuminating-tile consisting of a body provided with parallelintersecting rows of octagonal light-openings, and between thediagonally-opposite sides of such octagonal openings having smallersquare openings, lenses adapted to and fitted into such lightopenings,and cement placed between the sides of each lens and the contiguoussides of its opening, substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this18th day of December, A. D. 1889.
